Many screening tools are available in the public domain to assess a variety of symptoms related to impaired mental health. These tools can be used to quickly evaluate for mood, suicidal ideation or behavior, anxiety, sleep, substance use, pain, trauma, memory, and cognition (TABLE). Individuals with poor mental health incur high health care costs. Those suffering from anxiety and posttraumatic stress have more outpatient and emergency department visits and hospitalizations than patients without these disorders,1,2 although use of mental health care services has been related to a decrease in the overutilization of health care services in general.3
Here we review several screening tools that can help you to identify symptoms of mental illnesses and thus, provide prompt early intervention, including referrals to psychological and psychiatric services.
Mood disorders
Most patients with mood disorders are treated in primary care settings.4 Quickly measuring patients’ mood symptoms can expedite treatment for those who need it. Many primary care clinics use the 9-item Patient Health Questionnaire (PHQ-9) to screen for depression.5 The US Preventive Services Task Force (USPSTF) has recommended screening for depression with adequate systems to ensure accurate diagnoses, effective treatment, and follow-up. Although the USPSTF did not specially endorse screening for bipolar disorder, it followed that recommendation with the qualifying statement, “positive screening results [for depression] should lead to additional assessment that considers severity of depression and comorbid psychological problems, alternate diagnoses, and medical conditions.”6 Thus, following a positive screen result for depression, consider using a screening tool for mood disorders to provide diagnostic clarification.
The Mood Disorder Questionnaire (MDQ) is a validated 15-item, self-administered questionnaire that takes only 5 minutes to use in screening adult patients for bipolar I disorder.7 The MDQ assesses specific behaviors related to bipolar disorder, symptom co-occurrence, and functional impairment. The MDQ has low sensitivity (58%) but good specificity (93%) in a primary care setting.8 However, the MDQ is not a diagnostic instrument. A positive screen result should prompt a more thorough clinical evaluation, if necessary, by a professional trained in psychiatric disorders.
We recommend completing the MDQ prior to prescribing antidepressants. You can also monitor a patient’s response to treatment with serial MDQ testing. The MDQ is useful, too, when a patient has unclear mood symptoms that may have features overlapping with bipolar disorder. Furthermore, we recommend screening for bipolar disorder with every patient who reports symptoms of depression, given that some pharmacologic treatments (predominately selective serotonin reuptake inhibitors) can induce mania in patients who actually have unrecognized bipolar disorder.9
